provide specific error information

Will be fixed in next release.

vitepress dev is normal

It won't be. You likely haven't opened the right page.

You can do something like DEBUG='*' npm run docs:build and it will show you the last file where rendering failed.

I haven't tested the DEBUG='*' npm run docs:build but it does say which file had the problem.
But annoyingly it's not pointing to the right line. I don't know if it's because of the frontmatter offset or because it's simply hard to know where the </sometag> is missing.

but it does say which file had the problem

Yeah it was added in recent releases.

But annoyingly it's not pointing to the right line

Unfortunately, that's not quite possible because markdown-it doesn't have an AST. We will need to use something like remark for sourcemaps support but it doesn't properly work with Vue.
